Functions ¶

func Evaluate ¶

func Evaluate[T function.Inputs](t *testing.T, synth function.SynthFunc[T], scenarios ...Scenario[T])

Evaluate runs the synthesizer function with the provided scenarios and asserts on the outputs.

Types ¶

type Assertion ¶

type Assertion[T function.Inputs] func(t *testing.T, s *Scenario[T], outputs []client.Object)

func AssertionChain ¶

func AssertionChain[T function.Inputs](asserts ...Assertion[T]) Assertion[T]

AssertionChain is a helper function to create an assertion that runs multiple assertions in sequence.

func LoadSnapshots ¶

func LoadSnapshots[T function.Inputs](t *testing.T, dir string) Assertion[T]

LoadSnapshots returns an assertion that will compare the outputs of a synthesizer function with the expected outputs stored in snapshot files.

Scenarios that do not have a corresponding snapshot file will be ignored. To generate snapshots, set the ENO_GEN_SNAPSHOTS environment variable to a non-empty value.

So, to bootstrap snapshots for a given fixture/scenario: create an empty snapshot file that matches the name of the scenario (or fixture if using LoadScenarios), and run the tests with ENO_GEN_SNAPSHOTS=true.

type Scenario ¶

type Scenario[T function.Inputs] struct {
	Name      string
	Inputs    T
	Assertion Assertion[T]
}

Scenario represents a test case for a synthesizer function.

func LoadScenarios ¶

func LoadScenarios[T any](t *testing.T, dir string, assertion Assertion[T]) []Scenario[T]

LoadScenarios recursively loads yaml and json input fixtures from the specified directory.
